Physico-chemical characteristics of topsoil for contrasted forest, agricultural, urban and industrial land uses in France.
Soil quality is related to soil characteristics such as fertility and contamination. The aim of this study is to assess the effect of land use on these soil characteristics and to confirm the following anthropisation gradient: (i) forest, (ii) grassland, (iii) cultivated, (iv) orchard and vineyard, (v) urban vegetable garden, and (vi) SUITMA (urban, industrial, traffic, mining and military area...
متن کاملTopsoil characteristics of three contrasting New Zealand soils under four long-term land uses
Marton (Argillic Perched-gley Pallic, Typic Endoaqualf), Ohakune (Typic Orthic Allophanic, Typic Hapludand), and Westmere (Mottled Mafic Melanic, Mollic Hapludalf) soils with differing structural vulnerability were compared at matched sites under different land uses. Topsoil samples (0-10 cm) from indigenous forest (>50 yr), permanent pasture (>50 yr), pine plantation (>20 yr), or arable croppi...
متن کاملMineralogy, physico-chemical properties and industrial testing of ArazGoney kaolin deposit for ceramic and tile industry
Arazgoni Kaolin deposit is located in East Azarbaijan Province, about 18 km south of Qara Aghaj, the center of Charoymaq city. The area under investigation, in the geological zoning of Iran, is a part of the Urmia-Dokhtar volcanic-plutonic belt. Most of the study area is composed of volcanic rocks with Oligo-Miocene dacite-andesitic composition which have been strongly altered by hydrothermal a...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولComparison of Carbon and Nitrogen Sequestration in Soils Under Plantations, Natural Forest and Agricultural Farm Land Uses in Arjan Plain in the Fars Province
The carbon sequestaration by plants and soil is one of the easiest and the most econimical ways to reduce atmosphere carbon. This study was conducted on the planted land use of Fraxinus rotundifolia, Cupressus arizonica, obinia pseudoacacia L., Elaeagnus angustifolia, Cedrus libani, and Quercus brantii (persica) in the Arjan plain of Fars province. For each plantation land use, there were three...
